Product details
Overview
AT17C512-10PI from Atmel is a 512-kilobit serial EEPROM FPGA configuration memory with 5V ±10% industrial supply range (−40°C to +85°C), 15 MHz max clock frequency, programmable reset polarity, and system-friendly READY pin. It serves as nonvolatile configuration storage for SRAM-based FPGAs including Xilinx XC4000™, Spartan®, Virtex™, Altera FLEX®, and Atmel AT40K/AT94K devices in master serial mode.
For engineers reviewing the AT17C512-10PI datasheet, AT17C512-10PI pinout, AT17C512-10PI application, or AT17C512-10PI equivalent, key selection criteria include industrial temperature support, 8-lead PDIP package compatibility, cascading CEO capability, in-system programmability via SER_EN-controlled 2-wire interface, and direct integration with FPGA CCLK/DIN/INIT/CON signal chains without external controllers.
Technical Context
The AT17C512-10PI implements a serial-access configuration memory architecture synchronized to FPGA-provided CCLK, using CE, RESET/OE, and CLK to directly control address counter enablement and DATA output tri-state behavior. Its internal EEPROM cell matrix supports single-bit serial readout with automatic power-on reset of the address counter.
It features dual write-protect inputs (WP1/WP2), programmable reset polarity stored in EEPROM, and a cascading CEO output that enables daisy-chained configuration of multiple FPGAs or higher-density arrays. The READY pin provides open-collector power-good indication tied to internal power-on reset timing.

Applications
| Industrial PLC Configuration | Xilinx Spartan® System Boot |
|---|---|
Use Scenario: Reconfigurable logic modules in factory automation controllers require reliable, field-upgradable bitstreams after power cycle or firmware update. IC Role / Device Role / Timing Role: AT17C512-10PI stores and serially delivers full configuration data to Spartan® FPGA upon power-up, triggered by CCLK and controlled by INIT/CON signals. Use Value: Industrial temperature rating (−40°C to +85°C) and PDIP package ensure long-term reliability in uncontrolled cabinet environments. | Use Scenario: Embedded vision systems use Spartan® FPGAs for real-time image preprocessing; configuration must load before sensor interface initialization. IC Role / Device Role / Timing Role: AT17C512-10PI acts as master serial configurator, driving DIN while synchronized to CCLK and asserting READY to gate FPGA startup timing. Use Value: READY pin provides deterministic power-good signal, eliminating race conditions between FPGA logic activation and supply stabilization. |
| Altera FLEX® Legacy Upgrade | Multi-FPGA Telecommunications Shelf |
Use Scenario: Field-deployed telecom baseband units based on Altera FLEX® FPGAs require drop-in replacement of obsolete PROMs with extended lifecycle support.

Use Value: Pin-compatible 8-lead PDIP footprint and 15 MHz CCLK support maintain full timing compliance with legacy FLEX® configuration protocols. | Use Scenario: High-density signal processing shelves integrate multiple FPGAs sharing a common configuration bus for synchronized boot. IC Role / Device Role / Timing Role: AT17C512-10PI devices are cascaded via CEO→CE connections to deliver sequential bitstreams across four FPGAs in daisy-chain topology. Use Value: Cascading CEO output eliminates need for external address decoding or multiplexing logic, reducing BOM count and board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar FPGA configuration memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT17LV512-10PI | 3.3V ±10% supply only; lower ICCA (5 mA vs. 10 mA); reduced FMAX (10 MHz vs. 15 MHz in military range) | Requires 3.3V system rail; not suitable for 5V legacy designs or mixed-voltage boards | Select only if target FPGA operates at 3.3V and system power budget prioritizes lower active current |
| XCR3064XL-10VQG44C | Not a configuration memory - CPLD with integrated configuration logic; no serial EEPROM function | Cannot replace AT17C512-10PI as standalone configurator; requires redesign to embed configuration logic | Not a functional alternative; included only as commonly misidentified part in legacy Xilinx toolchains |
Compared with AT17LV512-10PI, AT17C512-10PI delivers higher clock tolerance and 5V compatibility essential for industrial FLEX® and AT40K systems; neither part is pin-compatible with XCR3064XL-10VQG44C, which serves a fundamentally different architectural role.

FAQ
What is the operating voltage range for AT17C512-10PI?
The AT17C512-10PI operates at 5V ±10%, supporting industrial temperature range from −40°C to +85°C. This specification ensures compatibility with legacy 5V FPGA systems and avoids level-shifting requirements in mixed-signal control boards where AT17C512-10PI serves as the primary configuration source.
Does AT17C512-10PI support in-system programming (ISP)?
Yes, AT17C512-10PI supports ISP via its 2-wire serial interface when SER_EN is pulled low. This allows field updates of FPGA configuration bitstreams without removing the device from the PCB - a critical capability for AT17C512-10PI deployments in inaccessible or safety-critical industrial enclosures.
How does the READY pin function on AT17C512-10PI?
The READY pin on AT17C512-10PI is an open-collector output driven low during internal power-on reset and released (tri-stated) upon completion. When used with a 4.7 kΩ pull-up, it provides a hardware-synchronized signal to delay FPGA startup until VCC stabilizes - a key timing control feature unique to AT17C512-10PI among 512-kbit configuration EEPROMs.
Can AT17C512-10PI be used in a daisy-chain configuration?
Yes, AT17C512-10PI supports cascading via its CEO (Chip Enable Output) pin, which goes active-low when its internal address counter reaches maximum. In a chain, CEO of one AT17C512-10PI drives CE of the next, enabling seamless expansion beyond 512 kbit - a verified capability documented in Atmel Application Note 0437 for multi-FPGA systems.
What package type is used for AT17C512-10PI?
AT17C512-10PI uses an 8-lead plastic dual inline package (PDIP), designated 8P3 per Atmel's ordering information. This through-hole package maintains mechanical and electrical compatibility with legacy AT17/ATT17 PROM sockets and supports manual rework in low-volume industrial assembly environments.
